Donor-acceptor relations influence on the modern spring wheat varieties photosynthetic system activity

In this paper, we consider two ways for obtaining hymatomelanic acid extraction into conventional Soxhlet extractions: directly from the peat and from the dry product of humic acid. The results of the study of the elemental composition of humic and hymatomelanic acids are presented, their similarities and differences are analyzed. In order to study the effect of humic and hymatomelanic acid preparations on the growth processes of spring wheat, a vegetation experiment was conducted. Peculiarities of biological action of the solutions and hymatomelanic and humic acids of different concentrations in spring wheat varieties “IREN” were investigated. The paper presents a method for determining the ash content of the studied peat, as well as, calculations of the economic feasibility of using preparations based on the hymatomelanic acids.

Abstract To study the effect of sodium Selenite application different methods on the yield of spring wheat varieties, depending on the conditions of water supply, a series of vegetation experiments in accordance with the methodology were carried out. The object of the study is spring wheat of the Zlata variety (Triticum aestivum L.). It was found that the effect of selenium on the yield of wheat of the Zlata variety depended on the method of its application and the conditions of water supply. With optimal water supply, the positive effect of selenium on the yield of spring wheat plants was revealed with both methods of applying sodium selenite. It was found that in conditions of drought, the positive effect of selenium was obtained with both methods of using sodium selenite. The greatest efficiency of selenium is obtained in foliar processing of plants. The increase in grain weight in this variant was 1.4 times. The increase in the share of the agronomic significant part of the wheat crop yield to 36% is shown, which indicates the decrease in the negative effect of drought on the formation of spring wheat yield when using foliar processing of plants.

Positive Effect

This article presents the results of a study of spring wheat with the application of biological products. The positive effect of drugs on growth processes and productivity has been established. The conditions of spring wheat cultivation with the use of biologics and their influence on the yield of spring wheat were studied. The purpose of our research was to study the effect of biological preparations on the efficiency of growing spring wheat in light chestnut soils. Results of the presented studies on the impact on yield using growth stimulants and strains: flavobacterin 30, mizorin 7, strain 5S-2, strain 8 on spring wheat varieties: Esther, Lada, Lubava, in the Astrakhan region for 2016-2018. The results showed that when seeds were treated with growth promoters and strains, almost all variants increased their yield.
